WILLIAM GEORGE SHEPPARD, OF 'MCCOOIQ NEBRASKA.

VISE.

SPECIFICATION forming part f Letters Patent No. 416,959, dated December 10, 1889. Application filed August 29, 1889. Serial No. 322,374. (No model.)

To all whom t may concern.-

Be it known that I, WILLIAM GEORGE SHEP- PARD, of McCook, in the county of Red Willow and State of Nebraska, have invented a new and useful Improvement in Vises, of which the following is aspecitication.

My invention consists in a new and iinproved vise, which is more particularly intended for the use of jewelers, and for all other delicate work, and which will be hereinafter fully described andY claimed'.

Referring to the accompanying drawings, Figure 1 is a side view of my improvement. Fig. 2 is a horizontal section on line 2 2, Fig. l; and Figs. 3 and 4 are detail views ofthe seat-plate. l

The same numerals of reference indicate corresponding parts in all the Iigures.

Jewelers, diamond-setters, dentists, mathematical-instrurnent makers, and the like often ,find it necessary to fasten delicate articles while undergoing repairs in a vise. In the ordinary vise delicate articles are often defaced and injured by being squeezed too tight in order to secure sufficient hold. I obviate and overcome this difficulty by my invent-ion, which I will now describe.

l indicates the body of an ordinary vise, which is clamped to the bench and has the jaw 2 formed integral with it.

3 indicates the sliding-jaw, and 4 the ordinary screw for raising the lower jaw. I form both the jaws with a horizontal deep recess 5 G, the recess 6 of the jaw 3 registering with the recess 5 of the jaw 2, as shown. `In the recess 6 of the lower jaw lits the metal seatplate 7, having a threaded rod S, extending from the center of itsinner edge and passing through a horizontal aperture 9 in the lower jaw. On the outer end of this threaded rod S nut 10 is screwed, to hold the seat-plate 47 to the recessed jaw 3. To the inner edgeof the seat-plate is secured a curved spring 11, havingthe curved free ends, which, when the plat-e 7 is placed in the jaw 3,1est against the spring 11 pushes the plate 7 outward, so that its outer edge will enter the other recessed jaw 2, while its inner edge rests in the rei cessed jaw 3. The plate 7 thus forms a seat on which the article to be held in the vice rests, as shown in Fig. 3 of the drawings. The article is then grasped between the upper part of the recessed jaws above the plate 7. It will be seen that as the plate 7 prevents the article from falling' down between the jaws, forming a seat on which the article rests,.a delicate article can be firmly held by the jaws with a moderate pressure, while in the ordinary vise lit is necessary to grasp the article so tightly between 'the vise-jaws that it is often marred and injured. The plate 7, shown in the vise, will form a perfect seat for any article one-fourth of an inch in width, or less, while -for articles one-fourth to onehalf of an inch in width this plate' is removed by unscrewing the nut 10, and the wider seatplate shown in Fig. 4 substituted for it.

Other seatplates of varying widths can be employed for thicker articles; but the two above described will answer for most work.

It is obvious that any style of spring can y be placed under the seat-plate and will ansWer the same purpose without departing from the spirit of 4my invention, and also that my invention can be applied to any kind of visesuch as vises for blacksmiths, carpenters, cabinet-makers, machinists, &c.

Having thus described my invention, what I claim, and desire to secure by Letters Paten t,

1. The combination of a vise having one jaw formed' with the horizontal recess 5, the jaw formed with the horizontal recess, and a seat-'plate fitting in said recess G and having a spring behind its inner end, Substanf tially as set forth.

2. The combination of a visehaviug one jaw formed with the horizontal recess 5, the jaw formed with the horizontal recess 6 and the aperture 9, the seat-plate having the threaded rod 8,'the spring 11, and the nut l0,

substantially as set forth.
